 Baud rate：Setup working Baud rate of serial port, scope is 110~230400BPS.
Please set that baud rate is the same as that of user side equipment. Otherwise,
series port can't communicate.
 Data bits：Set working data bits of serial port, and the value can be 7 and 8.
Please set that data bits are the same as that of user side equipment. Otherwise,
series port can't communicate.
 Parity： Set the parity of serial port, and the values can be NONE, ODD or
EVEN. Please set that parity is the same as that of user side equipment.
Otherwise, series port can't communicate.
 Stop bits：Set stop bits of serial port, and the values can be 1 or 2. Please set
that stop bits are the same as that of user side equipment. Otherwise, series port
can't communicate.
 Device ID：number DTU, supplying one way of differentiating DTU for center
server. ID is fixed to be 8 numbers. If it is not full of 8 numbers, please add 0 in
front to make it full of 8 numbers.
 SIM Number： set mobile number which uses SIM card, and it is fixed to be
11 numbers. This parameter cannot change SIM card mobile number, but a kind
of way for center server to differentiate connected devices.
 Frame interval： Default is 200ms.
Data that DTU receive packet rules as following:
1. When serial port receives data whose length is more than appointed
buffer 2048 bytes, DTU will packet the receiving data and send to center
server.
2. Within the configured "frame interval" time, DTU equipment hasn't received
any serial port data, DTU will packet the received data and send to center server.
"Frame interval" time set too small, it can result one data packet to be
separated into more data packets. If set too large, it can result two or more data
packet to be packed into one data packet and send to center server together. If
adopt our default value, one packet will be separated into more or more packets or
it will be packed into one. If customer can't calculate the suitable value, please
contact our technical support engineer.
 Times of reconnection：Times of DTU to connect with center server, and the
default is 3. If trial times are more than configured "times of reconnection",
gateway will automatically power down and after a moment power on again,
